Question

一道英语题（主谓一致）
About one third of the populatian in Beijing and Shanghai______netizens,but in poorer areas,only three or four percent_____online.
A.is;is B.are;are C.are;is D.is;are

Answer 1

答案：B
翻译：京沪人口大约有1/3是网民,但是在更贫困地区,只有3-4%的人口上网在线.
此题考查population做句子主语时,主谓一致的语法.
1.相关规定如下：
如果主语指的是“全部的/整体的人口”,则谓语动词用单数形式；
如果主语指的是“部分的人口”,则谓语动词用复数形式.
如：The population of China is about 1.3 billion.
One-third of the population of China are farmers.
2.此两题中,主语population分别被one third和three to four percent所修饰,都是指“部分的人口”,所以谓语动词都用复数形式,即答案B为正解.
